MITSUBISHI WNMG080408-GH UC5115

High-Speed Cast Iron Roughing Specialist | 100% Made in Japan

Product Overview

The Mitsubishi WNMG080408-GH UC5115 is a high-performance, double-sided 80° trigon negative insert specifically engineered for the abrasive challenges of cast iron turning. Featuring the advanced UC5115 CVD coating, this insert provides industry-leading resistance to crater wear and plastic deformation. The robust GH chipbreaker is designed for heavy-duty roughing, making this indexable carbide insert the premier choice for CNC machining of gray and ductile iron in high-productivity environments.

Advanced Grade: UC5115 (The Cast Iron Expert)

The UC5115 grade is Mitsubishi's premium CVD solution specifically for cast iron. It features a specialized coating layer that offers incredible abrasion resistance, which is essential when dealing with the "sand" and abrasive nature of gray and ductile iron. This ensures a significantly extended tool life even at the high cutting speeds required by modern CNC machining.

GH Chipbreaker Geometry

The GH (General Heavy) chipbreaker is designed with a strong cutting edge to withstand high loads. In precision machining, stability is key; the GH geometry prevents edge chipping during heavy roughing passes and handles varying depths of cut with ease, ensuring superior chip control in cast iron materials.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 150 - 350 m/min (490 - 1150 SFM)
  • Feed Rate (f): 0.20 - 0.50 mm/rev (0.008 - 0.020 ipr)
  • Depth of Cut (ap): 1.0 - 4.5 mm

*Pro Tip: For gray cast iron, higher cutting speeds can be used to improve surface finish.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Cast Iron Beast" - Mark T., USA
"Switched to UC5115 for our ductile iron housings. The GH breaker handles the scale perfectly. Tool life is twice our previous brand."

⭐⭐⭐⭐⭐ "Reliable Roughing" - Lars H., Germany
"Very stable insert for high-feed roughing. The 6 edges make the cost-per-part unbeatable for mass production."

⭐⭐⭐⭐ "High Speed Quality" - Kenji S., Japan
"Consistency is why we buy original Mitsubishi. UC5115 keeps its edge even when we push the RPM. Excellent for gray iron."

⭐⭐⭐⭐⭐ "Great Service" - Liam F., Australia
"Arrived quickly in original packaging. These GH breakers are tough and don't chip on interrupted cuts."

⭐⭐⭐⭐⭐ "Unbeatable Cost" - Pavel D., Poland
"6 edges on a trigon insert is a huge advantage. UC5115 is our go-to for all cast iron CNC turning jobs."

Technical Q&A

Q: Is UC5115 suitable for steel turning?

A: No, UC5115 is specialized for Cast Iron. For steel, we recommend UE6110 or MC6025 grades for better results.

Q: What is the benefit of the GH chipbreaker?

A: The GH geometry provides a stronger edge designed specifically for heavy-duty roughing and interrupted cuts where stability is paramount.

Q: How many cutting edges does this insert have?

A: WNMG is a double-sided trigon shape, giving you 6 usable cutting edges, which is more economical than CNMG.

Expert Machining Tip: UC5115 vs MC5015

For General High-Speed Cast Iron work, UC5115 is excellent. If your application involves Highly Abrasive Ductile Iron, consider the MC5015 grade for even higher wear resistance.

Technical FAQ & Buying Guide

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.

When will my order ship and arrive?
